Questions we are asked in Mulberry Green
Would you work within a site like Essex County Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Mulberry Green off your patch?
No. Small places get the same service as large ones. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
What does an EI 60 rating mean?
Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Results are classified under BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. That rating only holds when the product is installed to its tested detail.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also phone 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
How we handle fire stopping in Mulberry Green
Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, often unnoticed. Those on your schedule are closed with the specified product. Most enquiries involve fire stopping installed outside its tested range and unsealed openings around new pipes and cables, across cable penetrations, small duct penetrations where the tested detail allows and linear gaps at wall heads. Searching for sealant specialists in Mulberry Green? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
A job near Mulberry Green is usually planned around one visit, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

From enquiry to sign-off
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Smaller jobs around Mulberry Green can be grouped with others nearby. You’ll have a fixed quote before work starts.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Preparing the site
- Send any specification or drawings in advance
- Point out parking and an unloading spot
- Send your site hours and access windows

Advice
Service penetrations in Mulberry Green buildings
There are a number of hotels within about 2 miles of Mulberry Green. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
Halls and meeting rooms at places like Church of St Mary sometimes gain new services, and any compartment wall crossed needs the specified seal. Wherever services are added at a hospital such as Essex County Hospital, 4.5 miles to the east of Mulberry Green, the compartment line has to be made good with the specified product. At a retail site such as Stane Retail Park (2.3 miles north-east of Mulberry Green), walls between units may be fire-resisting, so services added in a refit need the specified seal.

When to bring in a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Owners, agents and contractors
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed.
Risers and ceiling voids
Service risers and the voids above ceilings are where openings collect. Access is often tight, so we agree it with you in advance along with any permits your site needs.
Leave it or put it right?
Sealing behind the M&E trades area by area beats a sweep at the end. Openings are visible, access is open and nothing has to be taken down, and the right detail can be checked at the time. One visit to deal with every failing joint makes more sense than several trips to a place like Mulberry Green. Photos of every joint help us quote for the whole job.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.
